Letters Patent No. 104,269, dated June 14,1870.

COAL-STOVE.

The Schedule rei'eiredto in these Letters Patent and making part of thesame To all whom it may concern Be it known that we, Du Wrr'r O.CLARKalld HEN- RY W. CADY, of Sioux City, in the county of Woodbury andState of Iowa, have invented a new and use,- i'ul Improvement in Stovesfor Heating Purposes; and

.we do hereby declare that the following is a full, clear,

iuent in heating-stoves, whereby such stoves are ren-' dered moreeiiicientv for the purpose intended than stoves of ordinaryconstruction, and

It consists in forming chambers between the outer wall or casing of thestove and the lining, and in a damper inthe lining, and a dividingpartition, as hereinafter more fully described.

In the accompanying drawing- Figure 1. represents a' vertical section ofa stove constructed according to our invention, the section being;through the line a; a: of fig. 2.

Figure 2 is a horizontal section through the line 3 y of fig. '1.

Similar letters of reference indicate corresponding parts."

A is the outer wall or casing of the stove.

B is the-lining.

O is an air-chamber immediately surrounding the fire-box or furnace ofthe stove. Air is admitted to thischamber through the damper D.

' E is a damper in the lining B, which is opcrat ed by means ot the rodF. The damper D works onthis l0d+ By this arrangement a current of airmay be carried directly into the stove and in contact with the. fuel,-

whichmay be of advantage inlstartiug a fire, but ordinarily the air forthe support of combustion is admitted from the chamber Gthrough a seriesof holes This chamber H receives air from the outside through a seriesof holes, J, through the cylinder or casing A, just above the partitionI. The air which enters this chamber is discharged from apertures, L,through the top Kof the stove, which apertures communicate with thechamber.

' In this manner, air which has entered the chamber above thcfire-hox isheated and discharged into the room at the top of the stove. The currentwhich enters the chamber 0 through the damper for the support ofcombustion may be cut off, or nearly cut off, after the fire has beenwell started, so that, by this arrangement, there will be a constantflow of heatedaii" The air necessary for combustion will into the room.he introduced, while the disagreeable current of cold air on the floortoward the stove will be avoided. The latter inconvenience is felt inall cases when heatingstoves receive their air'at the bottom, as isusual.

- M is the door for the introduction of the fuel.

N is the smoke-pipe.

O is a cover over an aperture in the top of the stove.

These stoves may be made either round. or oval, andare adapted foreither wood or coal.

By admitting the air upon all sides of the fuel, through the orifices G,a more perfect and economical combustion of the fuel is produced than bythe ordinary method. 1

Having thus described our invention,

We claim as new and desire to secure by Letters .Patenty 1. The damper Ein the lining B of the stove, arranged to operate substantially as setforth.

2. In combination with the chamber C and H, the partition I, by whichthe two chambers are separated. arranged substantially as described.
